In a recent court case, it was found that during a period of 11 years, 893 people were selected for grand jury duty, and 42% of them were from the same ethnicity. Among those eligible for grand jury duty, 81% were of this ethnicity. Use a 0.05 significance level to test the claim that the selection process is biased against allowing this ethnicity to sit on the grand jury. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and provide a conclusion about the null hypothesis that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution.**Null Hypothesis (H₀):** p = 0.81**Alternative Hypothesis (H₁):** p < 0.81**What is the test statistic?** z = -29.71 (Round to two decimal places as needed.)**What is the P-value?** P-value = ______ (Round to four decimal places as needed.)

13. Are Seat Belts Effective? A simple random sample of front-seat occupants involved in car crashes is obtained. Among 2823 occupants not wearing seat belts, 31 were killed. Among 7765 occupants wearing seat belts, 16 were killed (based on data from "Who Wants Airbags?" by Meyer and Finney, Chance, Vol. 18, No. 2). We want to use a 0.05 significance level to test the claim that seat belts are effective in reducing fatalities. a. Test the claim using a hypothesis test.
In a recent study, researchers found that 40 out of 250 boys aged 7-13 were overweight or obese. On the basis of this study can we conclude that more than 15% of the boys aged 7-13 in the sampled population are overweight or obese? Use a 5% level of significance. 1) the appropriate null and alternative hypotheses; 2) the appropriate test; 3) the decision rule; 4) the calculation of the test statistic, and 5) your conclusion including a comparison to alpha or the critical value.
In a recent court case it was found that during a period of 11 years 868 people were selected for grand jury duty and 42% of them were from the same ethnicity.
